How to Block Cookies in Browser

The majority of you have probably heard of non-biscuit cookies, but you might not know what they are or how to use them. Web cookies have already been covered in terms of how they affect your privacy and how to control them through a website’s settings. However, this article provides you with step-by-step instructions for setting up cookies using the browser settings available in Google Chrome, Apple Safari, Mozilla Firefox, and Microsoft Edge.

What are cookies and why worry about them?

A cookie, a little file containing information about your computer and the actions you do on the website, is created and stored on your computer whenever you visit almost any website. Both the websites you visit and outside parties, including advertisers, have the ability to set and use cookies.

Website cookies are frequently required for the site to function properly or to enhance the user experience. For instance, they might assist an internet retailer in remembering your city or swiftly change a global website to your language. They can remember your login information, which is perhaps the most important feature because it saves you from having to enter it each time you visit a website where you have an account.

However, cookies from other services (sometimes known as “third-party cookies”) are typically utilised for analytics or targeted advertising. They can be used, for example, to determine which banners you clicked on or which items you browsed through in online shops. Since not everyone appreciates this kind of attention, most browsers allow you to block it.

How to block third-party cookies in Google Chrome

To block all third-party cookies in Google Chrome in one fell swoop:

  • Click the three dots icon in the upper-right corner, select Settings and go to Security and privacy → Cookies and other site data.
  • To block all third-party cookies, select Block third-party cookies.

If you want specific websites to gather both first-party and third-party cookies (some services, like Microsoft Teams, won’t function if third-party cookies are disabled), or if you want specific websites to not store anything at all:

  • Go to Settings → Security and Privacy → Cookies and other site data.
  • Scroll down to the Customized behaviors section.
  • Select Add next to Sites that can always use cookies or Sites that can never use cookies.
  • Enter the URLs in the relevant fields.
  • Check the box next to “Including third-party cookies on this site” if you wish the exclusion to apply to all cookies. This checkbox needs to be selected at the beginning because it disappears when in editing mode.

How to block third-party cookies in Safari

Third-party cookies are by default blocked by Safari. To double-check, in Safari for macOS:

  • Go to the Safari menu and select Preferences → Privacy.
  • Check that Prevent cross-site tracking is enabled.
  • Select Manage Website Data under Privacy for more detailed choices. Here, you may erase cookies and other data for specific websites as well as identify which websites store cookies and other data on your computer. Read more about How to Block Cookies in Your Browser.
